Connection of 230 V~ utilities should be carried
out by using insulated leads with 2.5mm² section,
in compliance with the applicable regulations in
force. The output terminals are marked with Ph
(Phase), N (Neutral) and GND (metal Ground).
In order for the electrical circuit
breaker devices to operate correctly, the gen-
erator is supplied with an output voltage at
230 V ~ related to its mechanical and electri-
cal mass. Should technical considerations
require a different configuration, remove the
yellow-green jumper linking the GND and N
terminals.
The generator has an internal protection against
overloads. It is preferable, however, to install a
thermomagnetic cutout switch for single-phase
network in the utility distribution control panel
with maximum capacity 12 A. It is good practice
to close the switch after starting the generator
and re-open it before switching it off.
Once the connections have been made, replace
the terminal block cover (Fig. 17 ref. 3).
5.5 Cut-off Relay connection
If a 230 V~ voltage is applied to the
generating set output, even for a short time,
the equipment may suffer serious damage.
On the distribution system of the 230 V~ power
line, immediately downstream from the generator
as indicated in fig.19, a cut-off relay (for example,
code 05423, optional) or another automatic
switch should be installed to isolate the generator
when the system is supplied 230 V~ mains
voltage.
Connect the relay (fig.19 ref. 1) as follows:
•
Connect the two wires of the 230 V output line
of the generating set (fig.19 ref. 2) to the PINS
1 - 3.
